Technical Information
To ensure autorun and distribution:
Modifies the following registry keys:
- [<HKLM>\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\ctfmon.exe] 'Debugger' = 'wmisrmgf.exe'
- [<HKLM>\SOFTWARE\Microsoft\Windows\CurrentVersion\Run] 'ctfmon.exe' = 'ctfmon.exe'
Creates the following files on removable media:
- <Drive name for removable media>:\Autorun.inf
- <Drive name for removable media>:\~Drivers\347hjs632dg.exe
Malicious functions:
To bypass firewall, removes or modifies the following registry keys:
- [<HKLM>\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\DomainProfile\AuthorizedApplications\List] '<SYSTEM32>\wmisrmgf.exe' = '<SYSTEM32>\wmisrmgf.exe:*:Enabled:TCPIP Host'
- [<HKLM>\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\AuthorizedApplications\List] '<SYSTEM32>\wmisrmgf.exe' = '<SYSTEM32>\wmisrmgf.exe:*:Enabled:TCPIP Host'
To complicate detection of its presence in the operating system,
forces the system hide from view:
- hidden files
blocks the following features:
- System Restore (SR)
- Windows Security Center
Creates and executes the following:
- <SYSTEM32>\wmisrmgf.exe <Full path to virus>
